The three of them have been playing happily together in the recent past, and Ben Mu Xiwan is still worried about whether Feng Chengyi will be infected, and Feng Chengyi is also worried about these problems.

But for a long time, Feng Chengyi was captured by Yu's innocent smile, and gradually left these things behind and no longer remembered them.

Den.

Feng Chengyi was practicing calligraphy, and suddenly the door was opened, he reflexively looked up, and found that it was Yu'er, so he smiled and said, "Okay, why did Yu'er come to the study?" ”

Seeing that little little bit ran to him with his little short legs, Feng Chengyi also smiled, bent down and hugged him in his arms, and said, "I see that you are also idle, why don't your father teach you to write?" ”

"Okay."

Yu'er was a little excited, trying to get the brush on the table, but he thought that his hands were short, and he couldn't do anything, he held this posture for a long time, and in the end, Yu'er lowered his head and was discouraged.

Feng Chengyi was happy to watch this little drama, a chuckle rose at the corner of his mouth, and he said happily: "Why, Yu'er gave up like this?" ”

Yu'er lowered her eyes and looked at her chubby little hands, and said sullenly: "My hands are too short, I can't do anything like you, I can get it with just my hand." ”

He clearly saw his mother's look of no energy in front of him, but as soon as he stretched out his hand, he could get what he had to climb onto the table and climb a few steps to get to it.

Feng Chengyi raised his head and smiled, stuffed the brush into Yu'er's little hand, and held his little hand himself, and slowly sketched a word on the white rice paper.

He was surprised by the font he had never seen before, and his eyes were full of adoration and pride.

And Feng Chengyi saw that he was almost done practicing, so he let go of his hand and said lightly: "Next, you have to rely on Yu'er to practice the font by herself." ”

"Good! I promise to get the job done!"

Twilight.

After dinner, Feng Chengyi sat on the roof, looking at the starry sky, and he suddenly thought back to the past few days.

Smallpox is a highly contagious disease, and it stands to reason that he has been playing with Mu Xiwan and Yu'er for the past few days, and his body has already been infected with smallpox, but his body is different from his shouting body.

This incident made him feel more and more strange, so he jumped off the roof and returned to the ground steadily, and he exclaimed in a deep voice, "Sword dye." ”

Suddenly, a black shadow appeared in front of Feng Chengyi, she knelt down on one knee, lowered her head and asked, "What is the matter with the prince calling Jian Ran to come?"

"You secretly go to the imperial doctor to come here, remember, don't be discovered by others on the way, and you must act in secret, so as not to cause an unnecessary fight."

"Yes!" Jian Dye retreated, and immediately went to find the imperial doctor in the palace.

Half an hour later.

The door of Feng Chengyi's study suddenly opened, and Jian Ran and an imperial doctor stepped through the threshold and walked in, saluting Feng Chengyi.

"I wonder what His Royal Highness the Crown Prince is doing when he is looking for a minion? It's His Royal Highness the Prince, what's the matter? ”

He walked around the desk, strode up to the imperial doctor, and said in a deep voice: "This prince asks you, do you know that the illness on the crown princess's body is other than the disease of smallpox, what else can cause that kind of illness?"

Feng Chengyi waited with some expectation for the imperial doctor to answer his question, but what he waited for was that the imperial doctor was confused, thinking about what that thing might be.

Although Feng Chengyi's patience is limited, he still has the patience to wait for someone to think of something, so he went back to the wooden chair, ate the tea that had just been made with the antidote, and waited.

Time passed little by little, but the imperial doctor still couldn't think of it, which made Feng Chengyi's patience gradually disappear, he pinched the teacup, and a crack appeared on the wall of the teacup.

As soon as he was about to speak, the imperial doctor immediately looked at him excitedly and said, "Prince! What is a minion?"

The imperial doctor was stunned, maybe he felt that he was too reckless just now, so he smiled at Feng Chengyi a little embarrassed, and immediately said seriously: "Your Royal Highness the Prince, there is another poison that can also cause the situation of the crown princess, but it is not as terrible as smallpox, it will just cause a rash." ”

"Got it, stand down."

The imperial doctor saluted Feng Chengyi again, then carried the box he was carrying, and ran away.

Feng Chengyi thought about it, and then thought of Qi Hui's head, before he went to find Mu Xiwan, she did everything possible to obstruct it, but he ignored her completely.

If she was really worried that he would contract smallpox, she would definitely keep obstructing it, but Qi Hui didn't, obviously, she knew that Mu Xiwan's illness was not smallpox at all, but the poison that the imperial doctor said was caused by it.

And Mu Xiwan is also vigilant on weekdays, Qi Hui will poison her The chance is so small that it is impossible to poison in the water and other places, the poison is only effective if it is taken internally, so what makes her let down her vigilance and will eat it is only a meal made in the back kitchen!

Thinking of this, Feng Chengyi immediately ran out, he counted the time, at this time, the emperor had just eaten dinner, and those slaves and maids had just come down to wash the dishes, so the cook who was in charge of cooking must still be there.

As he expected, he came to the imperial dining room, the cook was still there, and he was obviously about to walk out of the imperial dining room, so Feng Chengyi was waiting for him at the door.

The cook overflowed, and when he raised his eyes, he saw the prince standing not far away, his forehead was immediately covered with cold sweat, and he thought in his heart why he had provoked His Royal Highness the Prince.

He looked ahead with his eyes dodging, but it was impossible for him not to salute, so the cook walked up to Feng Chengyi with Feng Chengyi's gaze, saluted, and said, "His Royal Highness the Prince." ”

"Chef Li, do you know any suspicious characters in your imperial dining room recently?"

As soon as Chef Li heard that he was not looking for trouble, he suddenly became energetic, he lowered his head and thought about it, and suddenly, he thought of something, so he said.

"There are very few people coming to the imperial dining room these days, and I can remember a little clearly, probably because Concubine Qi's maidservant once sneaked in, and specially asked the slave where the princess's meal was."

"She said that the crown princess was playing with her concubine, and specially sent her to take a look, so the slave didn't think much about it, and pointed out to her where the princess's food was and continued to cook."

"It's Qi Hui again. It seems that this thing didn't run away. ”

Feng Chengyi gritted his teeth, his eyes suddenly became ruthless, the woman and child he was protecting on the tip of his heart were framed by Qi Hui's woman into that look, he really couldn't swallow this bad breath.

The cook glanced at Feng Chengyi with some trembling, maybe Feng Chengyi's appearance was very scary, and he wouldn't even leave.

"His Royal Highness the Crown Prince, is there anything else?"

When he came back to his senses, he frowned when he saw the cook's appearance, but he didn't say anything, he raised his sleeves, then turned around and left, going to Qi Hui's residence to find her.

Since it was Qi Hui who poisoned her, then Qi Hui must have medicine on her body, and when she refuses to write about her, Feng Chengyi doesn't believe it, he can't get back the antidote that belongs to their mother and son for Mu Xiwan.
